It cools back down when the water evaporates. But it doesn't do the oceans any good anyhow because thea heat also fuels algae blooms.

I doubt it will become popular because it involves waterproofing the enclosures, complicates maintenance staff access, and also carries the risk of water getting in and damaging the equipment.

There are other alternatives to AC. Using a cooling tower is a much better alternative to submerging the whole datacenter.

This is mostly aimed at large cloud providers such as Amazon, Google, and Microsoft. They can use units like this and take them up for scheduled maintenance every x years. What happens to some of the individual servers between maintenance is of less importance. The infrastructure can handle the failures and they can just turn off the affected servers if they cannot fulfill any role.
